System Description: Notes

• Front wiper relays (front wiper relay, front wiper high relay) are located in the IPDM E/R (intelligent power distribution module engine room).
• Wiper switch (combination switch) is composed of a combination of 5 output terminals and 5 input terminals. Terminal combination status is read by BCM (body control module) when switch is turned ON.
• BCM controls front wiper LO, HI, and INT (intermittent) operation.
• IPDM E/R operates wiper motor according to CAN communication signals from BCM.
